Low carbohydrate content against low fat – not just in calories

Not all calories have a direct effect on our weight

The diets are like the sand beside the sea and new ones are added every week. Who should watch? In a recent large-scale diet study, several diets have been observed for a longer period of time to identify which diet is progressing to weight loss. It has also been shown that weight loss is not just about calories. Although all participants received the same number of calories over a 20-week period, a particular group declined the most.

An American research team from the Boston Children's Hospital and the State University of Framingham attended and controlled overweight in 20 weeks following prescribed diet programs. During this time, body weight, insulin levels, metabolic hormones and calories burned were measured at regular intervals. It has shown that weight loss is more important than the number of calories. The results of the study have recently been published in the journal "The BMJ".

Obesity and obesity – a growing health problem

Overweight and obesity is a growing health problem, not only in America but also in Germany. Obesity promotes numerous heart disease, hypertension, diabetes and depression (see: Obesity can cause depression). Doctors and scientists are desperately looking for effective methods to overcome this phenomenon. Diets are good measures to lose body weight, but for many, success is short-lived. A few months later, weight is back, sometimes even more than before.

Which diet is better for weight loss?

Which diet is most effective for long-term weight loss? This question was answered by the US research team. The researchers compared three diets to a group of obese subjects over a 20-week period. Diet is provided entirely by the university to ensure that all participants receive the same number of calories.

Three diets – Same number of calories, different weight loss

Participants were divided into three groups. One group received a diet consisting of 20% carbohydrates, 40% carbohydrates in the second group and 60% carbohydrates in the third group. Although the number of calories was exactly the same in all three groups, participants from the low carbohydrate group showed the greatest reduction and maintenance of weight loss as long as possible.

Calories are not equal to calories

The researchers concluded that calories from carbohydrates lead to faster fat storage. "Carbohydrates increased insulin levels during the diet and led fat cells to store more calories," says research director. honey. David Ludwig in a press release on the results of the study. Increased storage will be available for the rest of the body less calories. The result: The metabolism slows down and hunger increases, so the nutritionist. From this situation, a rapid weight gain may occur.

Weight loss in the low carbohydrate group was significantly greater

As the researchers found, total energy expenditure in the low carbohydrate diet group was higher at 20 weeks. With the same average body weight and caloric intake, participants who followed a low carbohydrate diet burned about 250 kilocalories a day more than those with higher carbohydrate intakes. People who already had high levels of insulin at the start of the study were even more active. Here, the low carbohydrate group burned an enormous amount of 400 calories a day.

The carbohydrate insulin model

The study proves that the so-called carbohydrate-insulin model is suitable for the treatment of obesity. Researchers have been able to show that carbohydrate intake leads to higher insulin release. This promotes the accumulation of fat stores, slows down metabolism, prevents saturation and promotes a sense of hunger. "Our observations challenge the belief that all calories are the same for the body," summarizes second director Cara Ebbeling. (Vb)
